Confidant in Combo, good against which decks?

[kras2005]

I'm playing TPS and/or IT and/or Grim Long Combo at the moment. And I have tested a lot. But there is something I cannot have a good vision or grip at. I don't know what's best.

Against which decks is it good to have Confidant in your Maindeck?

Versus almost all decks, it is good to have it in play. But that's a difference. You don't want to draw it while you are trying to combo-out.

But why don't we all play it MB? You lose a few games due to Confidant, but you also win games from him. But it is very difficult to see exactly how many wins and loses it provides. Does anyone has a good percentage?

What's your opinion about this subject?

It's good against pretty much every deck in the format, save Grim Long and Belcher. Against control you have a threat that makes mini-tendrils a lot easier to pull off and continually replenishes your hand. Against Aggro-Control you have a 2cc threat that keeps drawing you cards that isn't affected by Chalice or Null Rod and can block in a pinch. Against Stax, it's another cheap permenant and way to find land.

It also allows unique board strategies, as you can board in ESG + 3-4 other men (Trinket Mage and Negator come to mind) and go beatdown if you feel so inclined.
